For those who want a tentacle hentai that lets nothing get in the way of the tentacles and sex, this is for you. While the series in Japan is quite popular spanning two games with loads of text, several doujins, and even a few books, with the h-anime here we are treated to the King of cookie-cutter plots. Mikoto, Sui, and Yamato are all special classmates at some school gifted with magical powers that they use to cast away demons. Well, one day an extremely powerful demon in the form of a humane-like horse, captures them and sends them into his hidden world of tentacles,
his only goal is to show them their true desires, controlling their mind and making Mikoto and Sui ultimately submit themselves to not only his tentacles, but himself as well.

Alright, getting the fancy setup out of the way there, simply put as a tentacle/monster/fantasy hentai fan, this is the hottest one I have ever seen. Since October of 2006, it's still remained as my number 1 favorite hentai. As I've stated before, if you truly want an enjoyable nonstop tentacle action packed title, Inyouchu takes the cake. The intro is about 5 minutes long and from there, it's basically 25 minutes of nonstop tentacle and horsedemon sex.

This was handled by Amour studios, pretty infamous for animating Sora no Iro, Mizu no Iro. Because of this, you can easily expect to see some fascinatingly smooth animations at work here. There are absolutely no stills to be found here at all and they do not repeat any scenes or shots unlike a lot of other hentai out there. That's impressive when you've got 25 minutes of dynamic sex going on. I also firmly believe the music in this one is the best I've heard in any hentai out there. It's incredibly soothing and very high quality, unlike most themes in hentai it doesn't sound out of place or just downright goofy. The sound effects are also dead on. The character designs are like most of Amour's stuff, a bit on the cute side. I think this adds a lot to Inyouchu and a level of innocence, while it's very vibrant and colorful, deep down it's all about the tentacle and demon sex.

Getting more to the sexual (more graphic in words) part here, it is very hardcore. Though, not something I'd exactly call an "extreme" hentai. The tentacles won't be poking out of the girls or anything, unlike Taimanin Asagi, Himekishi Lilia, or Sexy Magical Girl Ai to name a few. But Inyouchu is very hardcore in its own cute way. For those who have a fetish for lots of cum in their hentai, you will love this. There are up to 5 scenes of internal "cumbustions" as some say with the tentacles and the horsedemon where the girls are just pumped full of enormous amounts of juices (several seconds of inflation sometimes, again, not too extreme though), eventually the cum comes erupting out of the girls privates and right after that, the tentacles are back to work. Rarely do we see something like this in hentai as detailed as Inyouchu has done it, and they do it 5 times! The girls don't get killed or beat up or anything, with the exception of a short deflowering scene towards the beginning that I actually found to be pretty hot, despite not being a fetish of mine.

Well, there you have it. This review might be a bit too long for its own good, but I think I've stressed my point enough, I'm sure after reading this it's obvious this is my favorite! It's an absolute masterpiece, the only problem is, will we ever get a follow up episode? With so much material for the series out there in the form of books, games, and whatnot, it's just begging for more! The issue is Amour is a rather small studio and they've gone through a lot. But, I'm not going to stop crossing my fingers.

All in all, you want nonstop tentacle action with loads of cum and insanely cute heroines? Inyouchu is just that!

This h-anime wasn't as bad as I thought since I'm not into tentacles. I didn't get too aroused in the first half since it got the normal tentacle rape. But the more Mikoto gets non-stop fucked, especially by the Demon later, the more arousing it gets. I almost wished there was just Mikoto instead of this Sui ;3 Mikoto is the typical strong fantasy hero girl I like, proud and willing to fight demons to death. So it's even more interesting to see her get broken within those two episodes.
Especially the end was likeable and I was sad that it had to stop there -_-
This H-Anime surely has its bad moments and there is nothing such as like a good story, but it gets the more interesting the more you watch, I guess episode two is the one you are waiting for. A lot of tentacles, one demon and girls getting broken, if you are a fan of this, this will be an excellent h-anime for you.

This is one of the worst series I've seen. It's nothing but a NTR with a demon instead of some guy that never got a hug from his mommy.

The story is lacking anything but a demon raping and mind screwing two girls.

The art and sound are great. The H scenes are good. But the main characters are bland copies of every NTR victim (way to easily controlled by the guy and ultimately can't live without her attacker).

I did review thees out of order but it doesn't matter since none of them really go together with a story only the mains name is the same. This
title wasn't enjoyable
for me nor the series for that matter. But if you don't mind just watching rape scenes with no direction then this is the hentai for you.
